SY100ELT21LZG-TR

Translators, Level Shifters Overview

The SY100ELT21LZG-TR is a single differential LVPECL-to-LVTTL translator manufactured by Microchip Technology. It operates on a single +3.3V power supply and features a typical propagation delay of 2.0 ns with a maximum frequency of 275 MHz. The device provides 24 mA TTL outputs and utilizes an 8-lead SOIC package. It supports ambient operating temperatures from -40°C to +85°C and includes a VBB reference output for AC-coupled or single-ended interfaces.

Translators, Level Shifters Feature Summary

• Supports differential, single-ended, or AC-coupled input interfaces via the VBB pin
• Provides added stability under open input conditions by forcing the Q output low
• Compatible with positive ECL 100K logic levels

Translators, Level Shifters Applications

• Clock signal translation
• Data signal translation
• Low skew single gate design applications

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'TR' indicates tape and reel packaging containing 1,000 units per reel. Confirm the 'ZG' suffix corresponds to the 8-lead SOIC package with a temperature range of -40°C to +85°C. Ensure compatibility with the required +3.3V supply voltage before procurement.

Translators, Level Shifters Selection Notes

Select this component when translating LVPECL signals to LVTTL using a single 3.3V supply. It is suitable for designs requiring minimal space, low power consumption, and low cost. Verify that the 275 MHz maximum frequency meets system requirements.

Translators, Level Shifters FAQ

How does the device behave under open input conditions?

Under open input conditions, the /D pin is biased at a VCC/2 voltage level and the D input is pulled to ground. This forces the Q output low to provide added stability.

What interface options are supported by the VBB pin?

The VBB pin allows for a differential, single-ended, or AC-coupled interface to the device. If used, it should be bypassed to VCC with a 0.01 µF capacitor.
